Speaker protection circuit diagram

Speaker protection circuit diagram:

This is a Speaker protection circuit diagram for our amplifier. this circuit can save our speaker from unwanted burning. Maximum original amplifier got this circuit with amplifier section or power section. but when we make an amplifier using a local circuit, we have to use this type of protection circuit. normally transistor amplifier makes this burning problem.

this is the circuit to protect our speaker from burnt from voltage. this circuit needs 12 voltages. here this circuit needs 12-0-12 Ac voltage. but also we can use 12 dc voltage. this circuit for one side. that means only we can use it for one channel. If we use in stereo amplifier then we have to use 2 circuits.
